JAKOVA (also written DIAKOVA, GYAKOVO and GJAKOVICA)  , a town of Albania, European Turkey, in the vilayet of Kossovo; on the river Erenik, a right-hand tributary of the White Drin . Pop . (19o5) about 12,000, Jakova is the chief town of the Alpine region which extends from the Montenegrin frontier to the Drin and White Drin . This region has never been thoroughly explored, or brought under effective Turkish rule, on account of the inaccessible character of its mountains and forests, and the lawlessness of its inhabitants—a group of two Roman Catholic and three Moslem tribes, known collectively as the Malsia Jakovs, whose official representative resides in and coloured figure taken from living plants sent him two years previously from Mexico . The jalap plant has slender herbaceous twining stems, with alternately placed heart-shaped pointed leaves and salver-shaped deep purplish-pink flowers . The underground sterns are slender and creeping; their vertical roots enlarge and form turnip-shaped tubers . The roots are dug up in Mexico throughout the year, and are suspended to dry in a net over the hearth of the Indians' huts, and hence acquire a smoky odour . The large tubers are often gashed to cause them to dry more quickly . In their form they vary from spindle-shaped to ovoid or globular, and in size from a pigeon's egg to a man's fist . Externally they are brown and marked with small transverse paler scars, and internally they present a dirty white Jakova .
